Answer:  The given statement is FALSE.

Step-by-step explanation:  We are given to check whether the following statement is true or false :

"If the dimensions of a cylinder are doubled then its volume is quadrupled."

We know that

the volume of a cylinder with radius r units and height h units is given by

V=\pi r^2h.

If the dimensions are doubled, then the new dimensions will be

R = 2r  and  H = 2h.

Therefore, the new volume will be

V'=\pi R^2H=\pi \times(2r)^2\times (2h)=8\times \pi r^2 h=8V.

Thus, the volume of the new cylinder will be 8 times the original one, not quadrupled.

So, the given statement is FALSE.

A bag contains green marbles and red marbles, 36 in total. The number of green marbles is 1 more than 4 times the number of red
tatuchka [14]

Answer:

29

Step-by-step explanation:

Total marble = 36

Let red marbles be X

Then green marble is 4X + 1

And 4X + 1 + X = 36

5X = 36 - 1

5X = 35

X = 35/5 = 7

So, green marbles = 4X + 1

= 4(7) + 1

= 29

Copy the figure below onto a separate sheet of paper. Find the image of the figure under reflections in line m and then line t.
san4es73 [151]

The image of the figure under reflections in line m and then line t is shown below.

<h3>What is a transformation of geometry?</h3>

A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.

Reflection does not change the size and shape of the geometry.

The image of the figure under reflections in line m and then line t.

The reflection of the rectangle DEFG will be given in the figure.

More about the transformation of geometry link is given below.
